SVSound PB-12 Plus Subwoofer


SVSound PB-12 Plus Subwoofer


In today's economy, good value in audio is more important than ever. To that end SVSound (SVS) has created a line of subwoofers that address every possible need in home theater and music listening without breaking the budget. I recently spent some quality time with their big box model, the PB12-Plus. This superbly-built sub includes quality amplification, a sweet-sounding 12-inch driver and plenty of adjustability. I would venture to say that most bass issues can be resolved with the PB12's tuning and EQ controls.

The component that most affects the "feel" of your home theater and music listening experience is the subwoofer. To this end SVSound (SVS) has created a line of subs that addresses every need. If you want volume, they can do that. If you want a sub that plays low, they can do that. If you want a sub that doesn't take up too much room, they can do that too. The subject of this review, the PB12-Plus is definitely not the latter! This 12-inch box model is one of the largest and heaviest subs I've ever seen! Fortunately its price is not large. After spending some quality time with this beautifully made product, I found the price/performance ratio to be quite favorable.

Many subs will play loud and low but not many will do so with control and finesse. Once sound becomes non-directional, precision and clarity are what separate average subs from exceptional ones. Not only does the build quality affect this but adjustability does too. Most subs don't have the necessary controls to solve standing wave issues which cause peaks and nulls in the frequency response. You are left to adjust your room by adding bass traps or moving the sub to different locations. SVS has overcome this challenge by including controls for parametric EQ and a slick tunable port system with corresponding subsonic filters.
